Gold Price in CHF — December 2025

Across the 31 trading days recorded in December 2025, 24K gold (99.9% pure bullion) in Swiss Franc opened the month at Fr109.42 per gram and closed at Fr110.19 per gram, a net rose of Fr0.77 (0.71%) over the month. The average daily closing price for the period was Fr110.75 per gram, giving a useful benchmark for anyone auditing purchases or valuations made during this window.

Prices were most volatile around the extremes of the range: the month's high of Fr115.06 per gram was recorded on Friday, December 26, 2025, while the low of Fr108.18 per gram fell on Wednesday, December 3, 2025. That puts the intra-month trading range at Fr6.88 per gram, or 6.36% of the low, which is a reasonable proxy for how much short-term volatility affected the market this month.

Purity matters as much as timing when valuing gold. Using December 2025's closing rate, 22K gold (91.67% pure — the standard for jewelry worldwide) closed at approximately Fr101.01 per gram, 21K (87.5% pure, common across the Gulf) at Fr96.42 per gram, and 18K (75% pure, favored for its durability in fine jewelry) at Fr82.64 per gram. In trade units beyond the gram, the closing 24K rate converts to roughly Fr1,285.26 per tola (the standard unit across South Asia and the Middle East), Fr3,427.36 per troy ounce (the international spot-market unit), and Fr110,192 per kilogram.

Against the previous month's close of Fr109.10 per gram, gold gained 1.00% by the end of December 2025. Tracking this kind of month-over-month movement is one of the more reliable ways to judge whether a longer-term trend is forming, rather than reacting to a single day's price swing.

This data reflects raw international spot-market closing rates and does not include local retail premiums, making charges, or import duties that jewelers and dealers typically add. It is best used for portfolio audits, insurance valuations, scrap-gold ROI calculations, and understanding broad price trends — for an actual buy or sell quote, cross-reference against a local dealer's rate for the same date.
